An anonymous reader writes "Google announced today on its official blog the impending closure of a number of its less successful services. In addition to retiring minor features like Bookmarks List and Friend Connect, Google has outlined a plan to close down Wave. The experimental communication medium will go read-only on January 31, and on April 30 they will shut it down completely. Also on April 30, Google will be changing Knol so that individual knols are not viewable, though users will still be able to download and export them until October 1, at which point they'll disappear entirely. Google Gears is also getting the axe, as is Search Timeline and the Renewable Energy Cheaper than Coal initiative."
